Principle of Working of a Garage Door
Garage door systems use the principle of counterbalance to work. Here, a force is used to balance the weight of the garage door. This force is supplied by the garage door springs.
Components of a Garage Door and their Role in its Working
Garage Door Springs
Garage door springs are of 2 types. Torsion springs sit on top of the garage door while the extension springs are fitted on either side of the door. A torsion spring lasts for at least 10 years while extension springs last only for 7 years at the most. This is why torsion springs are preferred for their durability.
The lifting and lowering of the garage door are down by its cable mechanism.
Cables made of braided wirework are found at the bottom corners of the door. Along with the springs, they raise and lower the door by using their cable tension.
Every garage door has both vertical and horizontal tracks that help the door move along them. It is the tracks that guide the entire garage door to move in a straight and uniform manner. The thickness of the tracks depends on the weight of the door. Thick metal tracks prevent the door from warping or bending.
To move along the tracks, the garage door needs rollers. These rollers can be made up of nylon or steel.
The hinges of a garage door help its sections to bend and drawback as it opens and closes.
Working on the Garage Door
In a torsion spring system, the torsion springs are mounted horizontally just above the opening of the door. When the door lowers down, the cables make the springs twist and store energy. When the door opens, the springs unwind and release the energy that helps the door to get lifted.
In the extension spring system, the springs get stretched when the door is closed. When the door opens, they release the stored energy to lift it.
The Inner Workings of an Automatic Garage Door
An automatic garage door uses a button on a radio remote to open or close it. This button sends a radio signal when pressed to the garage door opener. The door opens only if its radio receiver gets a matching signal from the remote control.
In some cases, the garage door opener system interacts with a keypad that is placed on the outside of the garage wall. This keypad will send the radio signal only when the right digital code is fed, in order to open the door.
For safety, automatic garage doors must use a photo-eye sensor to sense obstructions in their path.
Contact garage technicians for installing a new garage doors for safety purpose.
Types of Garage Door Openers and their role in its working
The type of opener decides the nature of the working of the garage door. There are several types of openers like screw drive, belt drive, chain drive and jackshaft.
In the screw drive opener, an electric motor rotates a screw that uses a slider to open and close the door. In the chain drive openers, the motor is connected to a rear sprocket that in turn drives the chain to open or close the door using the slider. In the belt drive openers, the chain drives are replaced by belt drives
The jackshaft is the most durable but expensive type of garage door opener. It does not have overhead garage rails like the chain, belt, screw openers. Its motor turns the spring bar or torsion tube to lift or lower the door. This jackshaft will work only with a torsion spring system.
